ROCKEQRD, ILLINOIS ICE REMOVING: SYSTEM:

Application filed JuIy as,

This invention relates to certain new and useful improvements in coatingsystems to render airplane fuselages, wings, propellers and the likeimmune to the formation of ice thereon. One of the principal objects ofthe invention consists of a system of this character having sprayapplicators arranged in advance of the different parts of the plane tobe coated either through a pressure system or by the natural velocity ofheadwinds, the suction formed by the tractor types of propellers and thelike.

Anotherobject of the invention contem lates the provision andarrangement of a orm of support for the coating system upon thepropeller for the plane whereby the antifreeze solution may beadequately applied without causing injury to or interfering with theoperation of the propeller. 4

With the above and other objects in view, the-invention further consistsof'the following novel features and details of construction, to behereinafter more fully described, illustrated in' the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of an airplane showing byfull and dotted lines the particu lar disposition of the system. I

Figure 2 is a top plan view of the showing the system in operation.

Figure 3 is a fragmentary elevation of the storage tank and compressionchamber of the system.

Figure 4 is an enlarged detail sectional view taken through the journalconnection for the system at the hub of the airplane propeller.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 plane indicatesgenerall the fuselage of an airplane, which as s own in Figure 1 of thedrawings is of the cabin variety monoplane having a wing 11 and thepropeller blade 12 disposed axially of the lon 'tudinal center of thefuselage in advance o the wing. The above is of the usual and well.known con struction followed by airplane builders and 1930. Serial No.$70,983.

is mentioned for purposes of illustration in bringing forward the noveladvantages of ofplanes will be coated with a suitable sol'ution eitherto prevent ice formation thereon or else to melt ofi previous formationswhen same overweight the craft.

The invention primarily resides in the provision of a tank or reservoir13 of the closed variety having a pressure gauge 14, a sight gauge 15, afilling plug 16- and a valve controlled connection 17 between its upperportion and a compressed air tank 18. The reservoir may contain asuitable solution for the purpose intended and V to be dischargedthrough a pipe section 19 having tributaries 20, 21 and 22. Pipesections drilled or otherwise provided with orifices or jets atintervals thereon and in communication with the respective pipe sections20, 21 and 22, are disposed immediately in advance of the wing, fuselageand propeller. v

The spray pipe located in advance of the propeller is provided with astub shaft 23 upon one end, inwardly projected for journal associationwith a bearing member 24: carried within a hub cap 25 for the airplanepropeller. The stub shaft 23 is drilled or otherwise provided withrightang'ularly intersecting passageways by means of which lubricant maybe introduced into the hub cap 25 behind the bearing 24. Sucharrangement will provide an adequate rotary form of support for thespray apparatus located in advance of the airplane propeller and fromwhich position the spray apparatus may not become displaced to hinder orotherwise interfere with the proper operation of the airplane propeller.As suggested from the illustrations of the invention in Figures 2 and 4of thedrawings, it is only necessary to have the spray apparatus for thepropeller extend or otherwise project to a distance equivalentunderstood that the system could be applied to equal advantage uponboats, automo iles, etc.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention, what is claimed is:

1. A coating system for vehicles compris- I ing a pressure dispensingreceptacle, pipe sections leading therefrom, and a spray pipe havingcommunication with the pi e sectlons having discharge openings locateimmediately in advance of the propeller blade and terminating at theaxis thereof.

2. A coating system for airplanes comprising a pressure dispensingreceptacle havin a multiplicity of pipe sections leading to di ferentportions of the plane, spray pipes having communication with the pipesections and disposed immediately in advance of the wings, fuselage andropeller of the plane, and the spray pipe r the propeller beingjournally associated therewith.

In testimony whereof I afiix my signature.

SWAN E. NORTON.
